Couldn't read everything as there were way too many long, drawn out posts but I have seen this theme of natural/wild vs. artificial/captive play out often on these forums and want to share my 2 cents on this, for what it's worth:
Information about natural/wild conditions is invaluable and I believe forms the basis of all that we try to provide for our captive animals. In some specific cases and areas, natural/wild conditions are the absolute best that we can hope to achieve. This should make sense. All living things have evolved their DNA to fit within their "natural" environment.
In some cases, deviating from these natural conditions can have harmful, even fatal consequences for an organism, like trying to grow carnivorous plants in a nutrient-rich medium.
However, in some other cases, I believe deviating from these conditions can be beneficial for 2 general reasons:
1. Technology. Humans living in wild, natural conditions would not live to be 80+ years old, on average. Technology has allowed us to improve on these conditions, develop "unnatural" medical treatments, etc. to prolong our lifespan. No fish eats fish flakes or pellets in the wild (at least to my knowledge ) but these have proven to be a more healthy and safe source of nutrition for many (not all) aquarium species.
2. Our goals as keepers and nature's/evolution's goals are not necessarily the same. Our know if goal as keepers is to keep our animals healthy so they can live as long as possible. Nature/evolution's goal is to allow organisms to adapt so they can live long enough to reproduce for the continuation of their species. In other words, nature wants organisms to be able to reasonably reproduce, but it doesn't want them to become too strong or live too long - this would throw ecological balance out of whack.
Conclusion: It is *extremely* important to know as much as possible about natural/wild conditions but it is not necessarily the end-all be-all for all situations and should be taken with some grain of salt when applied to captive care of organisms.
I also question when they compare longevity as well. It is difficult to say for wild, as predication skews the results.
I do not know if they can accurately gauge age by just catching a wild one. But it would not surprise me.
